About Rapater
Last updated 8 August 2026
Rapater is a risk calculator for trading signals. You paste a signal you were sent — from a Telegram channel, a friend, anywhere — and it tells you what taking that trade would actually risk, in your own money, using your own rules.
What it does
It reads the symbol, direction, entry, targets and stop out of the message. Then it works out the position size that risks the percentage of your balance you chose, what the loss would be if the stop is hit, and what each target pays for that risk. If the signal contradicts itself — a stop on the wrong side of the entry, say — it says so and refuses to produce a number, because there isn't an honest one to give.
What it does not do
- It never holds your trading funds. Your money stays in your own exchange account. Rapater connects with a key you generate that can place and manage orders and can never withdraw — a limit the exchange enforces, not one we promise — so nothing here can move funds off your exchange. Each Rapater account has its own crypto address, used only for paying for a seat. The balance you enter is a number you type: signed out, it stays in your browser; signed in, it is saved to your account so your rules can size trades.
- It does not sell signals and does not tell you whether to take a trade. It reports what the numbers say and stops there.
- It is not affiliated with Kraken, Coinbase, Hyperliquid or Telegram, or with any signal provider. Those names appear because they are the venues and channels the tool reads. It connects to Kraken and to Hyperliquid; the others are not connected.
Where it is now
The free calculator works and needs no account. Founding seats are on sale and trading is live: for members who connect an exchange key, Rapater places the long order and manages the stop and targets after entry. Provider report cards are still being built.
